This sound is very, very close to what I heard many years ago from my old
Sony TV (picture tube type) as the displayed picture changed. Was able to
clean it up with lots of ferrites on every cable.
I was sure glad to throw it away after I stripped down all the ferrites of
course.

Does anyone know whether the variation in sound on this recording is due to
the RFI changing or the receiver being tuned?
